Comparing and Ordering Numbers

Finding Bigger and Smaller Numbers

Comparing numbers helps us know which is more, less, or if two numbers are the same.

Using Symbols

We use “greater than” \((>)\), “less than” \((<)\), and “equal to” \((=)\) symbols.

Ordering Numbers

We can put numbers in order from smallest to biggest or biggest to smallest.

Real-Life Uses

Comparing and ordering numbers helps us figure out things like who has more toys or which number comes next.

Examples

  • Seeing that 9 is more than 6.

  • Putting the numbers 2, 5, and 8 in order from smallest to largest.

In a Nutshell

Comparing and ordering numbers helps us organize and understand more and less.
